Super Smoothie Suggestions

Hi all! :)

I finally got myself a blender and have recently started experimenting with different types of smoothies. I've been loving adding in my protein powder, avocados and different types of seeds etc but just wondered if any of you had some super awesome smoothie suggestions? Heading to the shops later to stock up on different fruits and veg (very keen to try a super green spinach smoothie!) so I'm trying to make myself a list of all different things to add in.

All suggestions welcome!
